I don’t trust it

Pros: Plenty of drive connections, easy install.

Cons: Probably caused apparent drive failures, unreliable drive power.

Other Thoughts: I bought this back in 2014 for a new i7 build. Seemed to work great, but one day I had an SSD die. The SSD was replaced under warranty and I reinstalled it, but then it happened again. I’ve had many people tell me they’ve never had an SSD fail. Now I’m gun shy, so I replace the SSD with a Samsung. A few months later it wipes too. Fortunately I had a full disc backup, so recovered and was ok. I replaced this PSU with a Corsair modular. Fast forward to a year ago...used this Rosewill in a new build, but few weeks ago a WD Black HDD started acting like it was failing. Rig would shut down and not start without pulling the plug for a few minutes, and then act like the drive wasn’t connected and I could hear it doing spin up cycles. Thought it might be motherboard, but now thinking this Rosewill PSU has been flaky all the time and may have been responsible for the SSD failure as well as this WD drive. Bottom line, I don’t trust it. I probably should have recognized this under warranty, but hey...if a PSU powers up the rig it’s good right? Let’s just say I’ll be investing in more trustworthy power supplies in future.

Quiet, Powerful, Enjoyable.

Pros: Quiet
Stays Cool
Lots of cables for everything I need and room for expansion.

Cons: None as far as I can tell.

Other Thoughts: I bought this back in Nov. 2014 along with a few other parts to gradually build myself a computer as I could afford it. I was a little leery about the cable length a lot of people mentioned being an issue, but even in my NZXT H440 (a pretty large case!) the cables perfectly reached everything with room to spare. Everything tucked away neatly with no issues and so far it's been the perfect little power unit for me. I'm just sad I can't order another one from here for my next build because it's out of stock.
